So basically the buzzer, 1 k ohm resistor and Arduino should be connected like this:Īrduino digital pin 3 –> Buzzer –> 1 k ohm resisotor –> Arduino ground(GND) pin. Remember to connect the buzzer the right way, the buzzer has positive and negative pins! Connect the other side of the 1 k ohm resistor to ground(GND) pin on the Arduino. If you have an Arduino Nano, look the the image in “Using an Arduino Nano”.Ĭonnect the positive side of the b uzzer to digital pin 3, then the negative side to a 1k ohm resistor. If you have an Arduino Uno(which most people have), connect the components with the help of the image below. 1 k ohm resistor(any resistor between 333 ohm to 1 k should be fine in this project).An Arduino(I used an Arduino Nano, any other is fine).I modified the code posted by Dipto and added the PWM-pitches in directly into the Sketch, so you don’t have to mess around with Arduino libraries! Today I found a complete post on how to play Super Mario Bros theme song on a piezo buzzer! It’s very simple and fun, and great as a beginner Arduino project.Īll fame goes to Dipto Pratyaksa for making the Sketch code and sharing it with us!
